Anthurium plant named ‘Rijn200128’

ABSTRACT

A new and distinct cultivar of  Anthurium  plant named ‘Rijn200128’, characterized by its upright and outwardly spreading plant habit; freely clumping growth habit; durable dark green leaves; dark pink to light red-colored spathes with light yellow-colored spadices that are positioned above and beyond the foliage on strong and erect scapes; freely flowering habit; and good inflorescence longevity.

Botanical classification/cultivar designation: Anthurium andreanum cultivar Rijn200128.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium andreanum, and hereinafter referred to by the name ‘Rijn200128’.

The new Anthurium is a product of a planned breeding program conducted by the Inventor in Schipluiden, The Netherlands. The objective of the program is to create and develop new compact, freely clumping and freely flowering Anthurium cultivars with strong roots, dark green leaves, attractive spathe color, and good inflorescence longevity.

The new Anthurium originated from a cross by the Inventor on Jun. 21, 1999 of a proprietary selection of Anthurium andreanum identified as code number 9515, not patented, as the female, or seed, parent with a proprietary selection of Anthurium andreanum identified as code number 9807, not patented, as the male, or pollen, parent. The cultivar Rijn200128 was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Schipluiden, The Netherlands in April, 2001.

Asexual propagation of the new cultivar by meristem culture in a laboratory in Belgium since April, 2001, has shown that the unique features of this new Anthurium plant are stable and reproduced true to type in successive generations of asexual propagation.

BRIEF SUMMARY OF THE INVENTION

The new Anthurium has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of the cultivar Rijn200128. These characteristics in combination distinguish ‘Rijn200128’ as a new and distinct cultivar:

-   -   1. Upright and outwardly spreading plant habit.     -   2. Freely clumping growth habit.     -   3. Durable dark green-colored leaves.     -   4. Dark pink to light red-colored spathes with light         yellow-colored spadices that are positioned above and beyond the         foliage on strong and erect scapes.     -   5. Freely flowering habit.     -   6. Good inflorescence longevity.

Plants of the new Anthurium can be compared to plants of the female parent, the proprietary selection identified as code number 9515. In side-by-side comparisons conducted in Schipluiden, The Netherlands, plants of the new Anthurium differed from plants of the selection 9515 in the following characteristics:

-   -   1. Plant habit of plants of the new Anthurium was more open than         plant habit of plants of the selection 9515.     -   2. Plants of the new Anthurium and the selection 9515 differed         in spathe coloration as plants of the selection 9515 had         orange-colored spathes.

Plants of the new Anthurium can be compared to plants of the male parent, the selection 9807. In side-by-side comparisons conducted in Schipluiden, The Netherlands, plants of the new Anthurium differed from plants of the selection 9807 in the following characteristics:

-   -   1. Plant habit of plants of the new Anthurium was more dense         than plant habit of plants of the selection 9807.     -   2. Plants of the new Anthurium had smaller leaves and spathes         than plants of the selection 9807.     -   3. Plants of the new Anthurium and the selection 9807 differed         in spathe coloration as plants of the selection 9807 had dark         red-colored spathes.

Plants of the new Anthurium can be compared to plants of the cultivar Pink Love, disclosed in U.S. Plant Pat. No. 11,021. In side-by-side comparisons conducted in Schipluiden, The Netherlands, plants of the new Anthurium differed from plants of the cultivar Pink Love in the following characteristics:

-   -   1. Plant habit of plants of the new Anthurium was more open than         plant habit of plants of the cultivar Pink Love.     -   2. Plants of the new Anthurium had larger leaves than plants of         the cultivar Pink Love.     -   3. Spathes of plants of the new Anthurium were flatter, thicker         and more durable than spathes of plants of the cultivar Pink         Love.     -   4. Plants of the new Anthurium had lighter pink-colored spathes         than plants of the cultivar Pink Love.
